“…SLA studies conducted in more naturalistic contexts (e.g., classrooms) have also found advantages for learning cognates (e.g., Cunningham and Graham, 2000;Tonzar et al, 2009;Vidal, 2011;Otwinowska and Szewczyk, 2019;Puimège and Peters, 2019), but have produced more mixed results (e.g., Rogers et al, 2015;Otwinowska et al, 2020; see Otwinowska, 2015 for review). Some evidence suggests that cognate facilitation may be contingent on formal training in cognate recognition (Tréville, 1996;Dressler et al, 2011), suggesting that learners may not always be aware of formal similarities.…”
